Konvizi’s “HEIC to PDF” tool is free, with no sign-up, no watermark and no file limit. All the processing happens in your browser, on your device: your files are never uploaded to a server, which makes it suitable for personal and confidential documents.
Drag your HEIC files into the area above or click “Choose files”.
Use the arrows to choose the order of the pages, then click “Create PDF”.
The PDF is assembled on your device: one page per image, ready to send or print.
HEIC is the default photo format on iPhones and iPads since iOS 11. Thanks to HEVC compression, a photo takes about half the space it would as a JPG, at the same quality.
Its drawback: outside the Apple world, it often will not open. Many Windows PCs, Android phones, websites and online forms still reject it.
PDF is the universal document format: it looks the same on every device, keeps its layout and prints without surprises.
A single PDF is far more practical than ten separate photos for sending an application, a supporting document or scanned papers.
Contracts, payslips, bank statements, tax returns: PDFs often hold sensitive information. With Konvizi they never leave your device, are stored nowhere and read by nobody. Most PDF tools copy pages without recompressing them: selectable text, links and quality are preserved.
Your files never leave your device. No upload, no storage.
No upload and no queue: the conversion starts right away.
As many files as you like, with no imposed size limit.
No sign-up, no watermark, no subscription.

Yes, completely. No sign-up, no watermark, no maximum number of files: you can convert as many files as you like.
No. Everything happens in your browser, on your device. Your files are never sent over the internet: nobody but you can see them.
Yes. Add as many images as you like and order them with the arrows: each image fills one A4 page, in portrait or landscape depending on its orientation.
The easiest way is to convert it: the resulting file will open everywhere. To stop your iPhone from saving in HEIC, go to Settings > Camera > Formats and choose “Most Compatible”.
Open your browser’s developer tools (F12 key), go to the “Network” tab and run a conversion: no request carries your file. The site also enforces a security rule (Content-Security-Policy) that forbids the browser from contacting any site other than konvizi.com, and konvizi.com is a static site with no service able to receive files.
Yes. Konvizi works in the browser of your phone or tablet (Safari, Chrome…) just like on a computer, with no app to install. Very large files are processed faster on a computer, which has more memory.
